I think @votdev dropped netatalk plugin support, since it is not in the official jessie repos.
Would be nice if a dev could fork and make the plugin work with the new datamodels and
host it together with the netatalk 2.2.5 package in the omv-extras repo.
(The debian sid 2.2.5 Version was working with earlier OMV 3.0 when i was testing it).
Or else would be a huge setback if people could not use there TimeMachine's after upgrading and
complaining and blaming OMV for it, which is NOT OMVs fault.
